Police say at least 12 people have died in the shootings at the Washington Navy Yard. D.C. Police Chief Cathy Lanier said during a news conference Monday that 12 people were confirmed dead. Lanier says people are being told to stay in their homes and out of the area as authorities search for two other possible suspects. One of the shooters has died. The police chief says officers are searching for two other people with firearms wearing military-style uniforms. She says there is no indication of a possible motive at this time.
The shooting prompted nearby schools to be put on lockdown. And planes at Reagan National Airport were briefly grounded so they wouldn’t interfere with police helicopters. Less than two miles away, security was beefed up at the U.S. Capitol, but police said there was no known threat there.

About 3,000 people work at the Naval Sea Systems Command headquarters. It builds, buys and maintains the Navy’s ships and submarines and its combat systems.
